Abstract
A general theory of neutron scattering (elastic and inelastic) is presented . It is applicable to the whole domain of slow neutrons and includes, as li miting cases, existing theories for thermal and cold neutrons and for the e lastic scattering of UCN. A new expression for the inelastic scattering cro ss section for UCN is proposed. It differs from the one usually used by con sistently taking into account re-scattering processes. Evidence for slight heating and cooling of UCN is given. (C) 2000 Elsevier Science B.V. All rig hts reserved.
